To all whom it may concern:

Be it known that we, GEORGE L. PATTER- SON and JAMES B. FARRELL,citizens of the United States, residing at New York, N. 1., haveinvented certain new and useful Improvements in Electric-LampReceptacles, of which the following is a full, clear, and exactdescription.

Our invention relates to improvements in electric lamp receptacles, theobject of the invention being to provide a superior construction, thevarious parts of which may be more readily assembled than in the past,the construction of which is such that shortcircuiting is preventedunder all conditions, especially in outdoor work, where rain is liable,in the ordin ry construction, to cause said short-circuiting. Instructures of this type corrosion of the metal parts is a thing thatcannot be avoided, and, in many instances, such corrosions produceshortcircuiting across the terminals. By our construction this isentirely avoided. Drainage is also provided to prevent the accumulationof water at points where such accumulation would produce the aforesaidshortcircuiting.

In the accompanying drawings-Figure l is a side elevation of thereceptacle assembled and with a lamp in place, Fig. 2 is a lan view ofthe lower section of the receptacle, Fig. 3 is a side elevation thereofwith the metal parts removed, Figs. 1, 5 and 6 are detail views. Fig. 7is a plan view of the porcelain base alone.

1 is a base of suitable contour and ordinarily made of porcelain, orother suitable insulating materia. 2 is a socket, screwthreaded toreceive a lamp 3, of the usual incandescent type.

44 are outwardly projecting flanges on socket 2. 5 is a clearance recessthrough the lower side of said socket.

6 is a terminal having bifurcated ends -6 arranged to extend partiallyaround the outside of the base of the socket 2, and bear upon theflanges 4-4 thereof, whereby by the use of suitable screws 77, both theterminals 6 and socket 2 are held in place and at the same time anelectrical connection between said parts is provided. 8 is anotherterminal, terminating directly under the center of the socket 2 in theusual manner, and against which a central terminal of the lamp properengages.

999 are the walls of the dam around the terminals 8.

1010 are the dams around the bifurcated ends of the terminal 6. Betweenthese dams 9 and 16 are drainage canals 1111, increasing in depth asthey extend away from the center.

The usual wire connections are made in the usual manner, customary withsuch devices, and no explanation is necessary.

12 is a cap-piece which overstands the base 1 when the receptacle isassembled, ready to receive the lamp.

In outdoor use water is liable to be driven into the space between thelamp and the surrounding wall of the cover 12. In the ordinaryconstruction this water accumulates within the receptacle and causesshortcircuiting and encourages corrosion. By our improved construction,no water is permitted to accumulate, since by the use of the drainagecanals 1 11 1, the water is instantly rawn off. The terminals 6 and 8are separated to such an extent that short-circuiting is practicallyimpossible.

It should be understood that the drainage canals 11-11 pass under thearms 6*6 of a sufficient depth to prevent any danger of short-circuitingby the presence of any water moving outwardly through said canals. Thedams 1O serve not only to prevent the driving in of water, but alsoserve to center the cap 12. This dam 10 also prevents the leakage ofcurrent from the part 6 across to the usual holding screw (not shown)located nearby on opposite sides when the receptacle is mounted readyfor use.

What we claim as new is 1. In an electric lamp receptacle, a porcelainbase, a metallic socket, a terminal electrically connected with saidsocket, another terminal extending to a point central with respect tosaid socket, and drainage canals in the porcelain base extendinglaterally from points below the socket to the outside of the receptaclebody.

2. In an electric lamp receptacle, a base of insulating material,terminals carried thereby and including a lamp socket, drainage canalsin the insulating base leading laterally from points adjacent to thefoot of the socket to the edge of the base.

3. In an electric lamp receptacle, a base of insulating material, asocket, a terminal having a bifurcated end partially embracing saidsocket and external thereof, another terminalprojecting into the-spacebelow said socket.

4. In an electric lamp receptacle, a base of insulating material, ametallic lamp socket carried thereby, external flanges at opposite sidesthereof, a terminal partially embracinn said socket, and an electricalconnection therewith through the medium of said flanges.

'5. In an electric lamp receptacle, a base,

of insulating material, a metallic lamp socket 7 carried thereby,terminals carried thereby, dams formed integrally therewith andprotect-ing said terminals and drainage canal's' from the center of saidreceptacle to the outer edges thereof.

6. In an electric lamp receptacle, a base of insulating material, asocket flanged outwardly at its lower end and arranged to be supportedby said insulating base, a terminal having a curved end conformingsubstantially to the outer Wall of the socket and arranged to rest uponand reinforce the flanged lower end of said socket, means for securingsaid parts together, and another terminal carried by said insulatingbase ing into the space within said socket.
